        Yes, [1]. For VMAC I'm just finishing iparp - ARP filtering
via rtnetlink. In the next days I'll finish testing and documentation.
Another reason Alexandre to be happy :)

- define medium_id for each interface

- optionally, enable all/proxy_arp without worrying for
problems (without this knowledge proxy_arp replies for
everything, i.e. by default it is assumed that each device is
attached to different medium)

        I already implemented rp_filter extension that is aware
of the medium_id values - useful for environments with rp_filter
protection and multiple subnets on interfaces attached to same
hub/medium (arp_prefsrc was simply a work-around which is not
